BACKGROUND: Respiratory syncytial virus (RSV) infection is an important cause of pneumonia mortality in young children. However, clinical data for fatal RSV infection are scarce. We aimed to identify clinical and socioeconomic characteristics of children aged younger than 5 years with RSV-related mortality using individual patient data. METHODS: In this retrospective case series, we developed an online questionnaire to obtain individual patient data for clinical and socioeconomic characteristics of children aged younger than 5 years who died with community-acquired RSV infection between Jan 1, 1995, and Oct 31, 2015, through leading research groups for child pneumonia identified through a comprehensive literature search and existing research networks...

Biological membranes allow the regulation of numerous cellular processes, which are affected when unfavorable environmental factors are perceived. Lipids and proteins are the principal components of biological membranes. Each lipid has unique biophysical properties, and, therefore the lipid composition of the membrane is critical to maintaining the bilayer structure and functionality. Membrane composition and integrity are becoming the focus of studies aiming to understand how plants adapt to its environment...

The close relationship between protein aggregation and neurodegenerative diseases has been the driving force behind the renewed interest in a field where biophysics, neurobiology and nanotechnology converge in the study of the aggregate state. On one hand, knowledge of the molecular principles that govern the processes of protein aggregation has a direct impact on the design of new drugs for high-incidence pathologies that currently can only be treated palliatively. On the other hand, exploiting the benefits of protein aggregation in the design of new nanomaterials could have a strong impact on biotechnology...

Trichosporon asahii is a ubiquitous fungus that has been isolated as part of human microbiota. There has been an emergence of this pathogen in recent years, causing superficial and deep seated infections. There are scarce reports of urinary tract infections in pediatric intensive care burn units caused by this agent. We describe the cases of 2 pediatric patients with prolonged hospitalization due to severe burns that had received several antibiotic courses for previous infections. Both presented sepsis secondary to catheter related urinary tract infection by Trichosporon asahii...

The kidney glomerular capillaries are frequent sites of immune complex deposition and subsequent neutrophil accumulation in post-infectious and rapidly progressive glomerulonephritis. However, the mechanisms of neutrophil recruitment remain enigmatic, and there is no targeted therapeutic to avert this proximal event in glomerular inflammation. The uniquely human activating Fc receptor FcγRIIA promotes glomerular neutrophil accumulation and damage in anti-glomerular basement membrane-induced (anti-GBM-induced) glomerulonephritis when expressed on murine neutrophils...

γδ T cells are non-conventional, innate-like T cells, characterized by a restricted TCR repertoire. They participate in protective immunity response against extracellular and intracellular pathogens, tumor surveillance, modulation of innate and adaptive immune responses, tissue healing, epithelial cell maintenance, and regulation of physiological organ function. In this study, we investigated the role of neutrophils during the activation of human blood γδ T cells through CD3 molecules. We found that the up-regulation of CD69 expression, and the production of IFN-γ and TNF-α induced by anti-CD3 antibodies were potentiated by neutrophils...

Persister bacteria tolerate bactericidal antibiotics due to transient and reversible phenotypic changes. Since these bacteria can limit the effectiveness of antibiotics to eradicate certain infections, their elimination is a relevant issue. Photodynamic therapy seems suitable for this purpose, but phenotypic tolerance to it has also been reported for Pseudomonas aeruginosa. To test whether any phenotypic feature could confer tolerance against both antibiotics and photoinactivation, survivors from exposures to light in the presence of methylene blue were treated with ofloxacin, an antibiotic effective on non-growing bacteria...

Spontaneous hemorrhage from hepatic tumors is an uncommon but serious complication. Recently, interventional radiologic (IR) techniques are being used increasingly in the management of these patients. We report our 16-year experience in managing spontaneous hemorrhage from liver tumors. Twenty-six consecutive patients were diagnosed with spontaneous liver hemorrhage between 1995 and 2011. Initial management was operative in eight, IR in six, and supportive in 12 patients. Of those managed operatively, five were segmentectomies; one hemihepatectomy; one wedge resection; and one packing who later died from coagulopathy...

BACKGROUND: Social cognition is severely impaired in schizophrenia. Emotion processing, attributional biases, and theory of mind are often impaired, as well as the understanding of shared social knowledge. So far, little is known about stereotype knowledge and endorsement in schizophrenia. SAMPLING AND METHODS: White patients with schizophrenia and matched healthy respondents reported both their personal beliefs and the predicted beliefs of other people toward Black (study 1) and Gypsy individuals (study 2)...

Salt-reduction in processed products has been proposed as a high-impact intervention for reducing the sodium intake at population level. A major limitation for this approach is its potential negative impact on the sensory characteristics of products. The current practice in sensory and consumer science involves single sip/bite evaluations, which may not properly reflect the sensory experience that occurs during product consumption. In this context, the aim of the present work was to compare single and two bite evaluations of consumer sensory and hedonic perception of salt-reduced breads...

The medial preoptic area (mPOA) is a brain structure classically related to both non-REM (NREM) sleep and maternal behavior. Although the dopaminergic system is known to play a role in the control of the states of sleep and wakefulness, its effects within the mPOA on sleep are still not clear. Microinjection of the dopamine D2 receptor antagonist Raclopride into the mPOA has been shown to promote nursing postures in lactating dams with no effects on active maternal behavior. We hypothesized that the facilitation of nursing postures may be also associated with the promotion of NREM sleep...

Allium sp. vegetables are widely consumed for their characteristic flavour. Additionally, their consumption may provide protection against cardiovascular disease due to their antiplatelet and antioxidant activities. Although antiplatelet and antioxidant activities in Allium sp. are generally recognised, comparative studies of antiplatelet and antioxidant potency among the main Allium vegetable species are lacking. Also, the relationship between organosulfur and phenolic compounds and these biological activities has not been well established...

Evidence from human neuropathological studies indicates that the levels of the neurotrophins nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) are compromised in Alzheimer's disease. However, the causes and temporal (pathology-dependent) evolution of these alterations are not completely understood. To elucidate these issues, we investigated the McGill-R-Thy1-APP transgenic rat, which exhibits progressive intracellular and extracellular amyloid-beta (Aβ) pathology and ensuing cognitive deficits...
